Monitoring and Debugging
Many of the tools traditionally used for debugging and monitoring applications do not carry over to FaaS, which creates a need for new solutions. Watchtower  monitors runtime invariants for FaaS applications. Borges et al.  design and evaluate multiple approaches to distributed tracing. Manner et al.  provide a combined monitoring and debugging solution for FaaS.
